Specification of Letters Patent. I Patented lay 16 Application filed March 16, 1920. Serial No. 366,329. I

' To all whom it may concern:

Be it known that JoHANNns RIEDEL, a subject of His Majesty the King of Great Britain, residing at Main Road, Pinnaroo, in the State of South Australia. Commonwealth of Australia, has invented certain new and useful Improvements in Tobacco Pipes, of which the following is a specification.

My invention relates to improvements in tobacco pipes, the object of the same being to'alter the internal construction of a pipe in such a manner as to prevent an excessive quantity of nicotine from entering the smokers mouth which said object is achieved by making special provision for the: reception of moisture and at the same time guarding the entry of such moisture from admission to the mouth piece.

In carrying the object of my invention into effect I form a space of relatively considerable area between the bowl portion of the stem, which are made separable from each other, and additionally I provide a collecting chamber for moisture in the bowlend of the pipe in addition to forming a separate smoke passage, whilst in the stem end I 1nsort a small length of projecting tube.

But in order that my invention may be better understood I will now describe the same by aid of the accompanying illustrative drawings wherein -Fig. 1 is a sectional side elevation of the pipe.

Fig. 2 is a view of the inner or front end or inlet of the mouth stem.

Fig. 3 isan end view of the bowl stem looking towards the bowl.

Fig. et is a section through bowl end on line 00-029.

In each of the illustrations similar letters of reference are used to denote similar or corresponding parts wherever they occur.

In the drawings ais the bowl of thepipe and may be of any suitable shape and extends rearwardly in the form of a bowl stem Z) approximately at right angles to the bowl, its extremity being guarded by a metal ferrule 0 if so desired.

In the outer end of the bowl stem a space is bored or drilled at d and is tapered or recessed slightly for the reception of the mouth stem hereinafter referred to.

The space (Z is in length well in excess of the requirements of the mouth stem and thus constitutes an intermediate air space or smoke chamber from which an upper smoke passage or hole 6 communicates with the bowl beneath which I form a collecting chamber 7 for the retention of moisture and nicotlne.

Referring now to the mouth stem g it will be seen that the forward end'is designed to fit into the opening d in the bowl stem and-is characterized by having a relatively large chamber it formed therein which likewise serves as an air chamber, smoke space, or collecting receptacle for moisture. This chamber communicates with the outlet smoke passage formed in the mouth stem, but instead of being in direct communication I provide a'projecting passage is which practically isolates the smoke inlet of the tube j from the walls of the smoke space it.

By means of my invention the smoke can readily pass from the bowl a to the outlet j, but necessarily has to traverse the intervening spaces formed by the chambers (Z and h, and 1n so doing the moisture which invariably accumulates between the bowl and the outlet is aiforded an opportunity of settling down and being deposited in the spaces above referred to so that clean dry smoke is obtained from the tobacco.

It will be seen that the correct construction is such that even though a relatively large amount of moisture may accumulate in the chamber there is little or no chance of its obtaining access to the smoker through the passage is even when the pipe is laid on its side or up-ended, but on the contrary when the pipe is smoked in a normal position with the bowl slightly depressed the excessive moisture will find its way into the collecting chamber f. The construction enables the two principal portions to be easily taken adrift for the purpose of cleansing the interior.

In the drawings I have shown the passage 6 as being separately drilled through the stem to the bowl and independent of the chamber f, but a modification of my invention consists in forming the bowl end substantially in the same manner as I have formed the mouth piece end, that is to say, the chamber d may be extended and shouldered, and instead of a separate recess such as 7 being drilled the extended portion d would serve the same purpose and the passa 'e 6 could be furnished with a projecting tu e corresponding to the integrally formed passage is already described, but I prefer that in all cases the tube 70 should be formed Cir and drilled as an integral portionof the structure.

I have indicated the alternative arrangement of a tube inserted in the bowl end by the dotted lines shown at Z. My pipe may be furnished with an absorbent tube as at present used in pipes of somewhat similar construction.

Having now fully described and ascertained my said invention, and the manner in which it is to be performed, I declare that what I claim is e A tobacco pipe comprising a bowl and a bowl stem having a smoke passage, an en larged air space between the end of the passage and the end of the stem, a portion of said space being reduced in diameter and projected beneath said passage and parallel to the latter, in combination with a mouth-piece having an annular reduced portion at one end thereof adapted to closely fit the walls of the enlarged air space in the stem, said reduced portion being substantially shorter than the depth of the said air space into which it is received, whereby a chamber is formed between the end of the inner wall of the air space and the adjacent end of the mouth-piece, the transverse sectionof the said chamber being equal to the full bore of the air space, an outlet smoke passage extending longitudinally of said mouth-piece and having its inlet end at the end of the reduced portion thereof and in axial alignment with the first named smoke passage, and a separate air space in the mouth-piece extending parallel to the smoke passage and communicating with the said chamber.

In testimony whereof I affix my signature.
